Verified key reference for the GMC 3500 HD — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| Sierra 2500/3500 HD | 2020–2024 | Smart-proximity (PEPS) | Hitag2 Ext / ID46E (earlier) → ID49 (later) — confirm by VIN | emergency blade — FCC HYQ1EA / HYQ1ES |
Security System & Immobilizer
GMC follows GM’s security ladder — VATS, PassLock, PK3/PK3+, ID46 Circle+ keys, and modern proximity fobs.
On the 3500 HD specifically we see: confirm by VIN. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

GMC 3500 HD Key FAQ
I lost the only key to my 3500 HD. What now?
We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site — no tow, no dealer wait.
My 3500 HD is push-to-start — can you program that outside the dealer?
Yes. Late models (2020–2024) use a proximity smart key — we carry the fobs and the programmer, and we cut the emergency blade.
